I thought I would update this thread with some more pictures. I went back and remounted the brass jet adapter. The water jet fits nicely into the adapter. I have been experimenting with different jet sizes and it seems that a 6mm jet is about perfect. The car just flies on 21 PSI of boost. I also remounted the DDS2 Flow Sensor so that the connection cable faces down per Richards recommendation.
The adapter protrudes just a little, but the water jet fits flush inside the intercooler tube.
